Description

Technical Field

[0001] The utility model relates to the field of wireless charging mobile phones, in particular to a back cover for wireless charging mobile phones. Background Art

[0002] With the popularity of large-screen smartphones, the high power consumption inherent in these devices has led to short battery life. The need to plug in and unplug power cords to recharge and the need to disassemble the phone case to replace the battery has become increasingly prominent. Improving the freedom of use of mobile phones and eliminating the need to plug in power cords and disassemble the phone's back cover to replace the battery has always been a key issue in the future of mobile phone battery life.

[0003] Wireless charging technology originates from wireless power transmission technology and can be categorized into low-power wireless charging and high-power wireless charging. Because energy is transferred between the charger and the device using a magnetic field, without the need for wires, neither the charger nor the device has exposed conductive contacts.

[0004] During wireless charging of the back cover of an existing mobile phone, charging easily causes the temperature of related components to rise, which can easily transfer heat directly to other electronic components inside the phone, affecting the use and lifespan of each electronic component. Similarly, the heat generated by other electronic components is also more likely to transfer heat to the wireless charging assembly, making it more susceptible to damage, causing the phone to overheat and affecting its normal operation. Utility Model Content

[0032] The present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0033] Embodiment 1:

[0035] Please refer to Figure 2-9, in this embodiment, the ventilation component 7 includes an arc-shaped ventilation groove 701, a baffle 702, a moving plate 703, and a guide rod 704.

A moving plate 703 is installed on one side surface of the baffle. A chute matching the moving plate 703 is formed on the surface of the mobile phone back cover 1. The baffle 702 and the mobile phone back cover 1 are slidably connected through the moving plate 703 and this chute. A guide rod 704 is slidably connected in a through hole formed on the surface of the moving plate 703. Both ends of the guide rod 704 penetrate through the moving plate 703 and are installed in the chute formed on the surface of the mobile phone back cover 1.

The fixing component 8 includes a plug rod 801, a spherical block 802, a plug board 803, a spherical rod 804, and a tension spring 805. A plug rod 801 is installed on the bottom surface of the moving plate 703. A spherical block 802 is installed at one end of the plug rod 801. A plug board 803 is installed on one side surface of the mobile phone back cover 1. A spherical rod 804 is slidably connected to the surface of the plug board 803. The spherical rod 804 is adapted to the spherical block 802. One end of the spherical rod 804 penetrates through the plug board 803 and extends to the outside of the plug board 803. A tension spring 805 is sleeved on the surface of the spherical rod 804 penetrating through the plug board 803. One end of the tension spring 805 is connected to the spherical rod 804, and the other end of the tension spring 805 is installed and connected to the plug board 803. Thus, ventilation treatment can be performed on the mobile phone back cover 1, enabling the mobile phone back cover 1 to dissipate heat during wireless charging, further improving the working efficiency of heat dissipation of the mobile phone back cover 1, and being able to fix the position of the baffle 702 when ventilating the mobile phone back cover 1, preventing the baffle 702 from affecting the ventilation effect of the mobile phone back cover 1.

[0036] Workflow: When wireless charging the mobile phone back cover 1, the magnetic induction receiving coil 3 on the wireless charging circuit module 5 performs magnetic induction processing. At this time, the wireless charging circuit module 5 processes the received magnetic induction. As the charging time gradually increases, the internal heat of the mobile phone gradually increases, and the mobile phone back cover 1 needs to be heat-dissipated. When heat-dissipating the mobile phone back cover 1, first pull the closing plate 602 inside the heat dissipation hole plate 601. At this time, the closing plate 602 slides inside the heat dissipation hole plate 601, and the closing plate 602 is gradually withdrawn. At this time, the heat dissipation holes of the heat dissipation hole plate 601 are gradually exposed. A filter screen is installed inside the heat dissipation holes, and the filter screen can filter dust and impurities in the air. At this time, the outside is connected to the placement groove 2 opened on the surface of the mobile phone back cover 1, so as to dissipate heat from the magnetic induction receiving coil 3, and the heat inside the mobile phone back cover 1 is dissipated. At this time, the heat dissipation strips 605 on the closing block 604 dissipate heat from the wireless charging circuit module 5 inside the inner cavity groove 4. When the closing plate 602 is being pulled, the closing plate 602 drives the tapered block 603 to scrape on the surface of the heat dissipation hole plate 601, so as to scrape off the dust attached to the surface of the heat dissipation hole plate 601. During the scraping process of the tapered block 603, through the compression spring 608 sleeved on the surface of the connecting rod 607 inside the sleeve rod 606, the compression spring 608 drives the connecting rod 607 to squeeze the tapered block 603, so that the tapered block 603 can fit more closely on the surface of the heat dissipation hole plate 601, thereby dissipating heat from the mobile phone back cover 1;

[0037] When the temperature of the mobile phone back cover 1 is too high, the operator pulls the baffle 702. At this time, the baffle 702 drives the moving plate 703 to slide on the surface of the guide rod 704. The guide rod 704 can guide the moving position of the baffle 702 to prevent the baffle 702 from shifting during movement. When the moving plate 703 slides on the surface of the guide rod 704, the moving plate 703 squeezes the return spring 705, and the return spring 705 can assist the moving plate 703 to return, thereby further improving the use effect of the device. At this time, the baffle 702 opens the arc-shaped ventilation groove 701, and the heat generated by the magnetic induction receiving coil 3 flows out to the outside through the arc-shaped ventilation groove 701 along the placement groove 2, so as to dissipate heat from the inside of the mobile phone back cover 1. When the baffle 702 is moving, at this time, the baffle 702 drives the insertion rod 801 to insert into the insertion plate 803. As it gradually moves downward, the spherical block 802 on the insertion rod 801 squeezes the spherical rod 804. At this time, the spherical rod 804 drives the tension spring 805 to deform, and the tension spring 805 can assist the spherical rod 804 to return. When the insertion rod 801 moves to a suitable position, at this time, the spherical rod 804 inserts into the slot opened on the surface of the insertion rod 801, so as to fix the position of the baffle 702 and make the arc-shaped ventilation groove 701 continuously ventilate.
